Green rated buildings have come to attract people’s attention, although there is a diffused
scepticism on whether their performance will comply with design expectations throughout the building’s
life. This paper provides a literature review on limitations of the rating system. According to previous
studies, barriers to facilitate certification schemes are still present in many countries. Some of the main
reasons are related to i) high costs, ii) insufficient knowledge about certification, and iii) time‐consuming
procedures. Inexperienced clients have difficulties in understanding the assessment process, as thirdparty
organizations do not have a suitable system to show guidelines and approaches for a client, such as
Pre‐Occupancy Evaluation. To date, researchers have conducted some studies on Post‐Occupancy
Evaluation in order to show the effectiveness of certified buildings. However, no attention has been paid
to Pre‐Occupancy Evaluation by the rating tool based on a customer’s self‐assessment which enables
clients to estimate costs, a rating level (or total point) and implementation time in advance, selecting
suitable options in the building information and requirements of each credit. This paper shows that
identifying existing obstacles is essential to further develop and improve rating systems so as to be more
acceptable in New Zealand. This preliminary investigation will also inform future studies on the
development of the Pre‐Occupancy Evaluation framework for New Zealand.
